Abstract: A telescopic steering column for a motor vehicle, with a base element on which a base element spindle is mounted so as to be rotatable about a base element spindle rotation axis, and with a telescopic unit which is guided linearly with respect to the base element and which has a telescopic unit driver which has a telescopic unit driver thread which engages with a base element spindle thread of the base element spindle. The telescopic unit has a telescopic unit spindle which is drivingly connected to a transmission element which is coupled to the base element spindle in a tangential direction with respect to the base element spindle rotation axis and is guided so as to be freely displaceable on it in the axial direction with respect to the base element spindle rotation axis.

Abstract: The invention relates to a method for determining a travel envelope along a planned travel trajectory (5), comprising the steps of: providing the travel trajectory (5), wherein the travel trajectory (5) comprises at least one curved trajectory segment (6, 7), wherein a curvature of the travel trajectory (5) has a constant sign, determining at least a first polygon (8), the circumference of which describes a vehicle contour (10) at a first vehicle position (11) on the trajectory segment (6, 7), and a second polygon (9), the circumference of which describes the vehicle contour (10) at a second vehicle position (12), establishing a pivot point (13) of the vehicle contour (10), which has the greatest distance from the curved line (14) during a movement of the vehicle (1) from the first vehicle position (11) to the second vehicle position (12), and approximating the curved line (14) by at least two legs (16, 17) of at least one triangle (18) which encloses the curved line (14), forming two convex polygons (22,

Abstract: A component, in particular a structural component for a motor vehicle, is disclosed. The component has a basic body formed from a hot-formable steel, which is provided with a coating at least in one partial region. The coating has a first layer of aluminum-silicon and at least one second layer, where the first layer is arranged between the basic body and the second layer. The second layer is formed from zinc-cobalt or zinc-manganese or from manganese. A method for producing a component, in particular a structural component for a motor vehicle, is also disclosed.
